DRIVING- ox, SHOE, AND WEDGE FOR LoooMorIvEs.

To all whom it may concern: 7 I

B it W- h3 i1 J ME A-AND RsW, a citizen of the United State's, Grafton in the county of Taylor and State of lVest Virginia, have inventedcertain new and useful Improvements in.D riving-Boxes, Shoes, and WVedges. for Locomotives, of which the following is a specification.

This inventionirelates to the 1 driving boxes. of locomotives, and its object is to provide. a box and a retaining means therefor so constructed that removal of the box may be readily effected without removing the wheels from the jaws of the frame of a locomotive.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing Figure l is a plan view of the box and the parts associated therewith, with the pedestal jaws of the locomotive frame in section on the line 11 of Fig. 2, and Fig. 2 is an elevation of the structure, the driving wheel being removed.

Referring specifically to the drawing, 5 denotes the pedestal jaws of a locomotive frame of standard type in which seats the driving box 6 through which the journal end of the driving axle 7, carrying the driving wheel 8, passes. Between the opposite faces of the jaws, and the respective ends of the box are interposed the usual wedge 9 and the shoe 10, and the box is fitted with a crown brass 11 shown dotted in Fig. 2.

The box 6 has outstanding end flanges 12 on the hub side, the opposite side being devoid of flanges. On the outer end of the wedge 9 is a laterally presented, outturned flange l3, and the corresponding end of the shoe 10 has a similar flange 14. The inner end of the wedge has a lateral, inturned flange 15, and the corresponding end of the shoe has a similar flange 16. The flanges 13 and 14 seat on the outer side of the jaws 5, and the flanges 15 and 16 seat against the rear face or inner end of the box 6. The flanges 12 seat against the flanged outer ends of the wedge and the shoe.

By the flanged construction of the box 6, the wedge 9 and the shoe 10, the box is securely held in place b t fifi th J LWS Specification of Letters Patent.

flanges of, the wedge and; theshoe being broken, tion, a Y a It will be noted that the-width of. the flanged end of the box 6 is notgreater. than the distance between the jaws 5, and hence, thebox can be slipped inward from between" the jaws after the wedge and the shoe are removed. It is therefore possible to remove the box for repairs to the crown brass, or end play, without the necessity of removing the Wheels from between the jaws of the frames. The box can be put in place, or removed, by simply taking the weight off the same, without removing the wheels. Another important feature of the design of the wedge and the shoe is, that in case of excessive clearance between the box and the wheel hub, the same can be eliminated by fastening a liner 17 to the flanged end of the shoe and wedge, provided, of course, if the end play liner or brass is still in good condition. The single flanged box, with the double flanged, or Z-shaped wedge and shoe, permit ready repairs to the box, the crown brasses, and end play brasses, and end play clearance can be reduced by the liner shown without removing the wheels.

I claim:

1. The combination with the pedestal jaws of a locomotive frame; of a driving box in the jaws having a transverse dimension the box would still be held inposithroughout its entire length which is not greater than the distance between the jaws, and means for locking the box between the jaws against lengthwise withdrawal.

' 2. The combination with the pedestal jaws of a locomotive frame; of a driving box in the jaws having a transverse dimension throughout its entire length which is not greater than the distance between the jaws, and retaining means for the box between its ends and the jaws, said means having outturned end flan es engageable respectively with the box and the jaws.

3. The combination with the pedestal jaws of a locomotive frame; of a driving box in the jaws having a transverse dimension throughout its entire length which is not greater than the distance between the jaws, and retaining means for the box between its ends and the jaws, said means having outturned 0 d flanges engageable respectively the wedge and the shoe each having three. 7

with the box and the jaws, and the box having outturned end flanges engaging one end of the retaining means.

4:. The combination with the pedestal jaws of a locomotive frame; of a driving box in the jaws and having outturned flanges at its outer end, a wedge and a shoe fitting between the jaws and the ends of the box, said wedge and the shoe having oppositely directed end flanges, the flanges at one end engaging the box and at the other end engaging the jaws, and the flanges of the box engaging one of the ends of the wedge and the shoe.

5. The combination with the pedestal jaws of a locomotive frame; oi a driving box in the jaws and having outturned flanges at its Copies of this patent may be obtained for five cents each,

outer end, a wedge and a shoe fitting between the jaws and the ends of the box, said wedge and the shoe having oppositely directed flanges at their ends, the flanges at one end engaging the box and at the other end engaging the jaws, and the flanges of the box engaging one of the ends of the wedge and the shoe, the box having a transverse dimension throughout its entire length which is not greater than the distance between the jaws.

In testimony whereof I affix my signature in presence of two witnesses.
